alex_joni: WEEEEE! I cut up a 4' x 8' sheet of 12 gauge this evening into little parts!!!
granthes: (if you read back ) you might try this code to test your encoders http://wiki.linuxcnc.org/uploads/pyvcp-dro2.hal
from this page http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
BigJohnT: let's see some pics
Got I/O? http://www.pastebin.ca/961646
Guest252 is now known as skunkworks
skunkworks: is that the futurlec?
that and the mesa card should give us 4 axis + 120 i/o
way cool i got same hdwr
you have a futurlec card?
yep, i think i got 2 years ago, were very cheap, came from thailand
cool box, lotsa squiggly lines
yes - you can still get them. There are some issues with the drive.. But I am sure they will be straitened out.
[02:58:57] <skunkworks> http://www.futurlec.com/PCI8255.shtml
thats it & the hal driver doesnt talk to the tiger chip, thats pretty unknown
hey, still cheap!
It works - there is just some issues with certain i/o configs - if I set all the pins to inputs... the computer hardlocks. :) jepler hopes to look at it this weekend if he gets a chance.
wow $80 is getting up there
still near a buck a point
SWPadnos thinks for 80 - you should just buy a another mesa :)
i bet you could etch your own, looks simple enough
if one were so inclined
there's got to be a PCI interface layout on the net somewhere
there were isa 8255 diy projects, never found a pci one, then found futurlec & stopped lookin
the futurlec uses a specialized pci interface chip, the 'tiger'
and there's 8255's hung pff the parallel port too
[03:14:14] <tomp2> http://shop.cpu.com.tw/product_info.php/cPath/38_180_508/products_id/5108
that's not quite as cool
definitely more diy-able though
i'm trying to figure out what the open graphics project used
i guess it's part of the fpga
whats teh 'XP10 PCI Bridge' on the schematic?
top left 2nd page
yeh htatsits between pci buys and the fpga's
yeah that sits between the pci bus and the fpga's
1x Secondary FPGA
Lattice XP10 (datasheet, mirror)
The Lattice XP10 non - volatile, reprogrammable FPGA (LFXP10e-5fn256c)is used for PCI communication.

Volari™ XP10 feature PCI Express X1/X8/X16 interface
so this opengraphics is an open design video card, cool
what is this volari xp10? it looks like a GPU
the co build lotsa grfx chips, i thought it might be the XP10 used on this opesgraphics card
its a pci interface
your right, its a grfx engine too
heh, drill down on the XP10 to find 'linux driver' , takes you to a page 'linux unified driver' thats sez 'no data' :-)
but goodies here http://fr.xgitech.com/sd/sd_opensource.asp
linux drivers for some chips sets
does ppmc can do io&servo on a same epp ?
I know you can stack several cards on one port (I don't know how many)
I think the card cage has 6 or so slots
how can it address those?
if you need 8255 and 8253, JDR has 2 models, isa and pci ( 8253 for programmable timer counter , 8255 for io )
I'm no expert, sorry, but I've worked on machines using ppmc
these had 3-4 of the cards all on one parport
[03:37:41] <cradek> http://www.mpm1.com:8080/machines/GandL/pictures/S1030216.JPG
anybody know how exactly ppmc address it's cards
the upper metal box is the ppmc cardset
looks like you can have 8 cards, this machine used 7
how ppmc address slot/cards?
what is the irc archeve address?
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-03-29.txt
[04:47:22] <SkinnYPupp> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/
does anybody know how ppmc is addressed
i dont understand the question
do you know how to use halcmd?
it should show up as ppmc.0... if you load the sample config
good morning all
good morning mr Joni
what's up captain?
oh, i have a couple of projects running
a l-system generator for a school project and an emc frontend for my company
i've also just completed another school assignment, a very fast sudoku solver :) http://arda.no-ip.org/Sudoku.hs
whats up on your end?
any fun machine projects?
hmm.. not really machine projects
is that haskell?
alex_joni: you there?
I cut a sheet of 12 gauge up into little bits yesterday with the cnc plasma cutter
thanks for all your help
we need proof obviously
some pictures and a couple movies from the action
I was too busy running it to take a movie but I was thinking about it
From yesterdays run I see I need to make a remote pendant for sure.
The CNC EMC part worked perfectly
happy to hear that
can you start the g code from a pendant?
we have a component called halui
which basicly enables you to do most things you could do from a regular GUI
but using hal pins
hmmm I have not looked at it yet
ok that is what I need
my linux machine is up in the shop so I can't look
[11:15:44] <alex_joni> http://www.linuxcnc.org/docview/2.2/html//gui_halui.html
Looks like it has everything I need, cool
finally got my irc setup on this box
is a u32 an unsigned number?
s32 is a signed number
ok, kinda thought so but it is real early for me on my first cup of coffee
hmm.. wouldn't know how that is
coffee or real early?
u drink tea for breakfast?
BigJohnT: I guess, or various jiuces
so to make a pick and place that runs over and over the same g code you could use halui to trigger the code based on an external input?
or you can make an o-word loop
with M66 waiting for the input :)
ok, that makes sense
just thinking out loud a bit
thinking is good
whee .. big fishee http://www.practicalfishkeeping.co.uk/pfk/pages/item.php?news=661
don't think I want to noodle that one...
[11:54:10] <BigJohnT> http://www.youtube.com/watch?v=biL-QcviQGk
I cut metal with my plasma cutter yesterday for the first time
how its going
yea, been waiting for this moment
everything works well
I used the drag tip instead of THC
what is drag tip ?
it keeps the plasma cutter a fixed distance from the work
THC is qiute complicated
normally for hand cutting
I have a floating mount so the drag tip worked great
your drag tip uses analog->digital conversing that you asked some time ago ?
as I remember you want to emc drive your Z axis
yes, that is next
actually I need to build a remote pendant next
hm, my ubunutu just booted once and mounted the whole file-system as read only
now it doesn't want to boot and says 'disk error' just after selecting OS un grub ??
better run to the store and get a SATA disk before it closes in 2h ??
* awallin is buying a new disk...
is mounting readonly normal sometimes? maybe for the times when the disk check is needed ( "mounted N times, disk check forced" ) or, before it is re-mounted r/w ?
in the early stage I think it mounts ro
yeh, thought so
could always install SMART tools as well
SWPadnos: Note: The safety inputs of these products are described as normally closed (N.C.), ie. with the guard closed, actuator in place (where relevant) and the machine able to be started.
an old idea: the 'security link', its a series of NC contacts , any one of which drops out the basic control voltage ( on old machines, a 24V ac supply ] X
door switches, hard limits, over/under voltage, fire sensor, etc
tom1: This is in respect to a specific safety relay.
It's manuals are not as clear as they should be
alex_joni: You play w/ safety relays alot?
hmm, alot might be exagerated
I have to debug safety circuits once in a while..
alex_joni: Take a look at the data sheet and installation instructions and tell me if you can make anything out of it, they're not as clear as they should be http://www.sti.com/relays/SR203M-A/index.htm
alex_joni: SR203AM01 is the ones I have
crap, need to register
alex_joni: They manuals for their other safety relays come with circuit exmaple sheets, just not this particular model... DOH!
alex_joni: no you dont
alex_joni: oh, use "nobody" as the userid
* alex_joni reads the installation instructions
seems similar to the ones I use
alex_joni: Note, this will be configured for MANUAL reset, not AUTO.
alex_joni: Sure, seems simular to the SR16 too, but a whole lot different too =)
I guess you are familiar with the general way this works?
at least the ones I have (have quite the same logic I think):
you power A1/A2
alex_joni: Of the SR16AM yes. The SR203AM is a differetn animal
and the same power is fed through all of the estop chain into S12 and S52
alex_joni: This out has outputs and inputs both NO and NC
NO inputs? where?
heh, keep reading =)
what is the Ubuntu version recommended for EMC2 right now? still 6.06LTS ?
JymmmEMC: I'm only looking at the wiring examples at the moment
awallin: at the moment, yeah
awallin: you can run the simulator in the newest version
7.10 is what I'm using
ok, so I'll just boot the new machine off the 6.06 cd then...
alex_joni: This is the SR16AM, and I completely understand this one, but it's manual has more concise information... http://www.sti.com/ltr2/access.php?file=pdf/4796.pdf
JymmmEMC: look at SR203 Circuit Diagramm
page 2 of the installing instructions (STI_IS_SR203M_57516_4.gxd.pdf here)
A1 and A2 are clear I presume
alex_joni: I can accoutn and understand 12 points except for: S11,s12,s52,s22
ok, lets leave S11 and S21 out for now
S12 and S52 are the two security channels
S12 is channel 1 (K1)
and S52 is channel 2
basicly it works like this..
when A1 & A2 is powered, S11 gives you the output power connection (e.g. 24V as on A1)
alex_joni: look at "Connectons" below the doagram
disregard that, it seems bogus
the idea is that you feed 24V through a series of NC contacts (your estop mushrooms and whatnot) and at the end you feed them into S12 and S52
there are 2 channels, because (at least in europe) you need to have everything redundant
each mushroom must have 2 contacts (one for channel 1, one for ch 2)
alex_joni: I really do understand the principals of a safety relay, I wired up the SR16 no problem. It's *THIS* specific relay (which has 8 additional connections) that's a bit puzziling in it's operation (eg what is what in which condition)
I think they really mean to express something else in the "connections" paragraph
S11 & S52 = safety input NC
that really means that if there's a wire between S11 and S52, then everything is ok
(which is exactly what I said before..)
alex_joni: Yeah, well I come to realize that in a safety relay if you think backwards, it backs sense
as it's designed to STOP things, not start them (for safety purposes that is)
JymmmEMC: I would wire it as I told you..
from S11 to your estop circuitry (all NC's) then to S12 and S52
when something opens it will open K1 and/or K2
alex_joni: This relay has a output that will say (as example) "Help ME" illuminates a lamp to let you know that ESTOP has been activated.
then after the ext. condition is gone, it won't get reset until you connect S34 with S11 I think
alex_joni: Reset is S12/S34 actually
can't be S12
well.. actually it's the same
alex_joni: It is, look at he "connections" chart
if you do S12/S34, then you can only reset if the external circuit is ok
but S12 is connected to S11 (through your estop circuit..)
No, you only want to reset when all conditions have been cleared
either way, if S12 or S52 have no power, you can reset all you want
nothing will happen
alex_joni: Look at the other PDF on that url I gave
if anything happens, then you should just toss out the SR203 ;)
alex_joni: pg2 of the other PDF
yeah, I saw that
(like the SR203 better)
alex_joni: Bottom of pg2 "Terminal Connections"
alex_joni: they are both the same device, different PDF's
hang on, you just told me to look at the pdf you sent me
that was the SR16AM
alex_joni: Sorry, we have a failure to communicate =)
[16:09:13] <JymmmEMC> http://www.sti.com/ltr2/access.php?file=pdf/2583.pdf
you never sent me that
alex_joni: The SR16 data sheet I was showing you that it has more information than the SR203
alex_joni: It was on the original url I gave you.
before you logged in
this is still SR16
stupid copy n paste
[16:10:59] <JymmmEMC> http://www.sti.com/ltr2/access.php?file=pdf/4089.pdf
ok, I have it open
that's a typical US schematic :P (only one channel used)
I'm not sure I understand what "Reset" is supposed to do there..
ahh, sorry.. yeah, I understood now (didn't properly read the NC contacts from the external K1 and K2)
* alex_joni hates when people name different things the same..
oh man.... http://www.mercurynews.com/ci_8739025?nclick_check=1
JymmmEMC: so what's not clear for you?
btw, that mercury link doesn't open here
[16:16:44] <JymmmEMC> http://www.google.com/search?lr=&ie=UTF-8&oe=UTF-8&q=Roadshow%3A%20%241%2C200%20a%20month%20fuels%20long%20commutes
yeah, found it..
what can I say.. join the rest of the world with high gas prices
well.. everyone with his own sexual preferences
alex_joni: Ok, before I stripped out the cabinet this was in, it was setup pretty cool... The BRB would light up when ESTOP was engaged. Also, the RESET button would light up when it was READY to be reset. I'm just trying to duplicate those functions again.
ok, BRB light you can connect to 41/42
and I would connect the RESET light to S12
alex_joni: where did you get S12 from in this respect?
just before the reset button
I know WHERE it is, but I mean the logic in your decision
I don't understand
is it possible that a relatively modern BIOS can't boot an OS that's installed at the end of a 250GB disc?
S12/S34 is RESET (input)
awallin: which OS ?
freshly installed ubuntu 6.06
JymmmEMC: no, S34 is RESET input
S12 is the input to channel 1
awallin: what happens when you try? Just get a blinking cursor?
JymmmEMC: yep, I get the bios screen and then a blinking cursor
awallin: you're missing the MBR
and in the diagram at page 2 (4089.pdf) the S12 is used to allow for pushing reset
boot the rescue disk, install grub
JymmmEMC: I did the partitions with the ubuntu installer, sholdn't it do that for me?
awallin: If it should, it didn't.
awallin: do as alex_jonisuggested
awallin: do as alex_joni suggested
hm, is grub on the install cd?
ok, I'll try
you have to update grub more than likely, but if you're missing the MBR, you just might not have a partition marked as bootable
* JymmmEMC cheats and just copies the MBR to a file anymore =)
hmh, how would I install grub from the install cd? apt-get install grub says grub is already the newest version
Backup MBR: dd in=/dev/sda of=/dev/sdb1/sda.mbr count=1 bs=512
Backup MBR: dd if=/dev/sda of=/dev/sdb1/sda.mbr count=1 bs=512
Restore MBR: dd if=/dev/sdb1/sda.mbr of=/dev/sda
(not the backup/restore of MBR does NOT work with extended partitions)
(note: the backup/restore of MBR does NOT work with extended partitions)
that's a different procedure
setting the bootable flag for the partition with fdisk did not work
awallin: you need to set it active, then run grub
awallin: try grub-install
hello from ubuntu...
yeah, just labeled the newly installed partition as bootable
the cd didn't do that for some reason...
great ( but check others )
278M of updates suggested by the package manager...
just look by running fdisk, no need to change what works
hm, ubuntu doesn't suggest the native resolution of my screen, where would I add that?
awallin_ubuntu: /etc/X11/xorg.conf :)
is a 12-24 tap rare? (how many stores must i visit?)
tomp: not rare, I have some
could you email me one?
got them from MSC, I think
sure, check your mail right now : )
ok, will check J&L in chicago ( i think msc owns them now )
yes, J & L is good- we use them all the time
[17:05:57] <alex_joni> http://www.earth-policy.org/Books/PB3/Contents.htm
has anyone here made worm-gears with a lathe?
we have at work on a CNC lathe
the worms anyway
ok, a lathe retrofit would be a nice project after I get this mill goign...
alex_joni: my current bedside book http://www.randomhouse.com/crown/livinglikeed/index.html
simple tricks to get greener
'making a worm gear' http://bbs.homeshopmachinist.net/showthread.php?t=20096
[17:20:06] <tomp> http://www.atmsite.org/contrib/JSAPP/wormgear/wormgear.html
some nice info out there
tomp: thanks. telescope drive was my intended use :)
's even a video, but its pay for
4 hours of gear hobbing, sounds like a fun evening
the heck with this 12-24 tap, a 5mm x 0.5 will do as well
system restart required.
how do I set the resolution in ubuntu. The GUI doesn't give me 1280x1024 as an option. Adding "1280x1024" to the xorg.conf doesn't help.
awallin: I'm not sure what the proper ubuntu way is
but sometiems adding a modeline helps
check /var/log/Xorg.log or whatever the logname is
it usually tells you what modes it tries
awallin: probably it wasn't able to read your monitor's info at install time, so the monitor specs in xorg.conf are wrong.
was there a latency-test somewhere with 2.2.4 ?
awallin: yes it's called latency-test :-)
i use the mach to 3 years would be possible to leave the interfaçe AXIS with some of the functions of the first screen of mach?
cradek: thanks. nice. I'm getting around 34000 for max interval on the 25us base thread, jitter 10000.
we don't use mach, so it's a bit unclear what you need
jack_live: since emc2 is free/open source software, you are free to modify it however you want. however, if you have very specific feature requests that you think might interest the rest of the users, you can file a request on sourceforge.
for example time of milling online
cradek, alex_joni: would a jitter of around 10000 for the 1ms thread and 17000 for the 25us thread be considered OK?
that seems fine to me
good but is possible show it online?
I don't understand what you mean by online
machine runing numbres in my eyes
good but is possible show it in realtime
sorry my english is bad
jack_live: it's not quite clear what you mean
(at least not to me)
Is the following as the use mach a long time that I had on the screen axis of some functions that are in mach eg time used in machining
sorry my english not strong
you mean how much time is left to machine?
(to finish the program?)
awallin: another page about worms for telescope drives: http://www.astronomiainumbria.org/advanced_internet_files/meccanica/easyweb.easynet.co.uk/_chrish/worms.htm
jmkasunich: thanks, looking.
I've made worm gears before, but relatively low tooth count (28) and I used a mill, not a lathe
gashed with dividing head, the free-hobbed
jmkasunich: nice link. I sent it to a coworker I am trying to get into machining :). Big telescope person that likes making mods for his scopes.
btw - our machine shop is finally getting a cnc. with a 'gasp' centroid control.
The head guy is old school machinist.. Doesn't like cnc. We have tried to get him to buy a older mill to fix up.. They could get 3 for the price they are paying for this mill
It will have conversational programming - so that will be neat to see. I have not been exposed to it before.

good night all
good night alex
up late micges?
yes, must check plan for tommorow stuides
here is just 11:30 pm :)
5:30 pm here
did you run any more cutting today ?
no, we bent the parts up and welded them together today.
I did plan some improvements today in material handling
now I'm cleaning up the mess down here in the beer cave
how is it handled now ?
not very well LOL
we put it up on saw horses
because it is portable I had to devise a portable support system for the sheet of steel
most of the time I will cut 3mm plate some times maybe 6.4mm
on ours mills sheet are handled by vacuum table
do you pressure the table to move the sheet?
like an air hockey table...
air is pumped from under the sheet
to hold it in place?
hold on I show you how that table look like, looking for pics
[22:56:54] <micges> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Micges
under table is 15 mm free space
and pump is about 1,5 KW
is that you in the picture
no, my stupid boss :P
what do your machines make?
this one is for "pertinax"
hmmm, what is that?
form in thin very hard material to make rows in paper
to make boxes easy to fold up

I live in the forest
hardwood forest of the ozark foothills
I can pee off my deck and no one can see me LOL
how far is to nearby town ?
must be nice =(
3 hours from any big cities
and neibours ?
I built my own house about 10 years ago with my wifes help
there are 6 houses on about 50 acres on my road
I live in the middle of 9 acres
and what is name of village ?
In Poland is hard to find that kind of place
Poplar Bluff, do a google map on 63901 the zip code here and look at the satilite photo
too many people too little land?
some sort of that
I live in Torun, central Poland
some pictures of the night lights of Torun look nice
yes its very nice
a long drive to your house!
from BC yes it is
you should make the trip from New Orleans to Anchorage when the AlCan highway was 1200 miles of gravel and pot holes....
now that is a trip or two
1 day 14 hours is what google says.... I think they mistake my pickup for a learjet!
4000km (2500 miles)
